Ya Goku is really strong -_- but let's not make this thread about how DBZ characters reign supreme over everything -_-. Seriously though I would have to say strongest person in like a close to realistic sense (like hand-to hand combat) would have to be Yuujiro Hanma. I mean this manga isn't Overly exaggerated its pretty realistic imo. Well Yuujiro is the main character father and he's The Worlds Strongest Creature o_o. Kills Polar Bears and 50ft tall elephants he has that whole creepy strong. Yuujiro a.k.a Ogre FTW

If you want more realistically, then I would say Takamaru from Hajime No Ippo, hes gonna be world champ!
